ANSWER
An exponential growth function.
EXPLANATION
The given function is

This function is of the form,

Since k is positive , the function will grow exponentially and fall asymptote to the negative x-axis.
As x-values becomes bigger and bigger positively, the graph grows exponentially.
For this case we must indicate an expression equivalent to:

By definition we have that the distributive property establishes that:

Then, applying the property to the given expression we have:

Thus, an equivalent expression is:

ANswer:

4/5 ,8/10, 16/20,
You multiply both numbers with the same number.
For ex. 4×2=8 5×2=10 so we have 8/10
6.6. 2.2*3= 6.6
i hope this makes since
